I'm too sore yet to try to learn the heel pivot properly. Carlsen measured repeated higher power (slight improvement) out of the heel pivot. Climo and Feldy suggest heel pivot for for easier pulling the disc on a line.

Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.
